Covering the theory of computation, information and communications, the physical aspects of computation, and the physical limits of computers, this text is based on the notes taken by one of its editors, Tony Hey, on a lecture course on computation given b
“The gift of Eva Pierrakos’s Pathwork has been with me for twenty years. It is the deepest and most effective spiritual work I have found, and it has helped me realize my dreams. Each time I read it, I am amazed at the depth and breadth of wisdom and love it teaches. It is a practical way of truth that will change your life.”—Barbara Ann Brennan, author of Hands of Light For more than twenty years, Eva Pierrakos was the channel for a spirit entity known only as the Guide. Combining rare psychological insight with an inspiring ision of human possibility, the Guide's teachings, known as the Pathwork, have influenced many key New Age thinkers who have studied at Pathwork centers in the United States and abroad. Now, the core teachings of the guide have been collected in one volume synthesizing the essential wisdom of the Pathwork. Under such headings as “The Idealized Self-Image,” “The Forces of Love, Eros, and Sex,” “Emotional Growth and Its Function,” “Real and False Needs,” and “The Spiritual Meaning of Crisis,” the Pathwork outlines the entire process of personal spiritual development. Unlike many over-idealized philosophies, the Pathwork confronts our devils as well as our anges, our all-too-human failings and petty ego concerns as well as our divine strengths. It shows us how to accept ourselves fully as we are now, and then ot move beyond the negativity, or “lower self,” that blocks our personal and spiritual evolution. It offers a practical, rational, and honest way to reach our deepest creative identity. “I would advise that this book be read with a willingness to take time to digest what the Guide says. This is not ‘light’ reading, thought it is Light reading, I assure you. I find an enormous compatibility between these lectures and Emmanuel's teachings. What a wonderful gift to a wonderful world.”—Pat Rodegast, author of Emmanuel’s Book
The author, a computer science professor diagnosed with terminal cancer, explores his life, the lessons that he has learned, how he has worked to achieve his childhood dreams, and the effect of his diagnosis on him and his family.
“YOU HAVE CHANGED MY LIFE” is a common refrain in the emails Walter Lewin receives daily from fans who have been enthralled by his world-famous video lectures about the wonders of physics. “I walk with a new spring in my step and I look at life through physics-colored eyes,” wrote one such fan. When Lewin’s lectures were made available online, he became an instant YouTube celebrity, and The New York Times declared, “Walter Lewin delivers his lectures with the panache of Julia Child bringing French cooking to amateurs and the zany theatricality of YouTube’s greatest hits.” For more than thirty years as a beloved professor at the Massachusetts Institute of Technology, Lewin honed his singular craft of making physics not only accessible but truly fun, whether putting his head in the path of a wrecking ball, supercharging himself with three hundred thousand volts of electricity, or demonstrating why the sky is blue and why clouds are white. Now, as Carl Sagan did for astronomy and Brian Green did for cosmology, Lewin takes readers on a marvelous journey in For the Love of Physics, opening our eyes as never before to the amazing beauty and power with which physics can reveal the hidden workings of the world all around us. “I introduce people to their own world,” writes Lewin, “the world they live in and are familiar with but don’t approach like a physicist—yet.” Could it be true that we are shorter standing up than lying down? Why can we snorkel no deeper than about one foot below the surface? Why are the colors of a rainbow always in the same order, and would it be possible to put our hand out and touch one? Whether introducing why the air smells so fresh after a lightning storm, why we briefly lose (and gain) weight when we ride in an elevator, or what the big bang would have sounded like had anyone existed to hear it, Lewin never ceases to surprise and delight with the extraordinary ability of physics to answer even the most elusive questions. Recounting his own exciting discoveries as a pioneer in the field of X-ray astronomy—arriving at MIT right at the start of an astonishing revolution in astronomy—he also brings to life the power of physics to reach into the vastness of space and unveil exotic uncharted territories, from the marvels of a supernova explosion in the Large Magellanic Cloud to the unseeable depths of black holes. “For me,” Lewin writes, “physics is a way of seeing—the spectacular and the mundane, the immense and the minute—as a beautiful, thrillingly interwoven whole.” His wonderfully inventive and vivid ways of introducing us to the revelations of physics impart to us a new appreciation of the remarkable beauty and intricate harmonies of the forces that govern our lives.
Noam Chomsky visited India in 1996 and 2001 and spoke on a wide range of subjects, from democracy and corporate propaganda to the nature of the world order and the role of intellectuals in society. He captivated audiences with his lucid challenge of dominant political analyses, the engaging style of his talks, and his commitment to social equality as well as individual freedom. Chomsky’s early insights into the workings of power in the modern world remain timely and compelling. Published for the first time, this series of lectures also provides the reader with an invaluable introduction to the essential ideas of one of the leading thinkers of our time.
